Problems solved by technology

At present, the chemical fertilizers used in litchi are mainly quick-acting fertilizers, which dissolve quickly after being applied to the soil. If too much is applied at one time, it will not only damage the root system, but also easily cause the loss of nitrogen and potassium fertilizers and the fixation of phosphorus fertilizers by the soil. Small and frequent fertilization is often used in production. In principle, fertilize 3 to 4 times a year
Litchi tree fertilization is different from common crops. It needs to apply fertilizer deep in the soil layer, which greatly increases the labor intensity and labor cost of farmers.
In addition, long-term chemical fertilizer application also makes the soil harden, the growth of litchi root system is hindered, and the growth volume is decreasing day by day. Due to insufficient nutrient supply, the plants will decline prematurely, the fruit will become smaller, the coloring will be poor, the quality will be reduced, and the yield will be reduced. big and small results

Abstract

The invention discloses liquid fertilizer special for litchi cultivation. The liquid fertilizer comprises 20mg / L of chitosan, 600mg / L of potassium nitrate, 300mg / L of ammonium sulfate, 200mg / L of magnesium sulfate, 100mg / L of calcium chloride, 10-20mg / L of boric acid, 0.2mg / L of copper sulfate, 50-100mg / L of urea, 50-100mg / L of niacin, 5-10mg / L of folic acid, 5-10mg / L of VB12, 5-10mg / L of plant growth regulator, 30-50mg / L of organic chelating agent and 1x103cfu / mL of bacillus subtilis. The liquid fertilizer is reasonable in raw material proportion, provides all nutrients needed by litchi for production and is high in permeability and solubility and capable of promoting litchi plants to grow vigorously.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and relates to a special liquid fertilizer for litchi cultivation and a preparation method thereof. Background technique [0002] Litchi is a typical evergreen fruit tree in subtropical regions. The root system has no natural dormancy period throughout the year, and its root absorption capacity is very strong. It replaces the fruiting mother branch by growing new shoots every year. New shoots need to be drawn many times a year, which requires a comprehensive supply of various elements. At present, the chemical fertilizers used in litchi are mainly quick-acting fertilizers, which dissolve quickly after being applied to the soil. If too much is applied at one time, it will not only damage the root system, but also easily cause the loss of nitrogen and potassium fertilizers and the fixation of phosphorus fertilizers by the soil. Small and frequent fertilization is often used in production. ...
